NASA Crater Detection Challenge

NASA’s Lucy spacecraft made headlines on October 16, 2022, as it successfully captured stunning images of the Moon’s surface during its first gravity assist flyby of Earth. This milestone is not only a testament to the spacecraft’s capabilities but also a crucial step in enhancing our understanding of lunar geography. Crater rims, which serve as essential landmarks for planetary science and navigation, present unique challenges for detection. Factors such as lighting variations, shadows, and the often fragmented appearance of crater edges make it difficult to accurately identify these features in images. As NASA aims to refine its next-generation terrain-based optical navigation systems, the agency is inviting innovators to contribute to a project focused on developing reliable methods for detecting and mapping these crater rims.

The project seeks to harness the power of visible-light cameras mounted on spacecraft to capture detailed orbital images of lunar terrain. By processing these images, NASA aims to not only detect crater rims but also match them to a pre-existing catalog of craters. This process is vital for estimating the spacecraft’s position relative to the lunar surface, thereby enhancing navigation accuracy during future missions. The challenge lies in the inherent variability of natural imagery, which can significantly affect the visibility and completeness of crater rims. With a total prize pool of $55,000, this initiative encourages participants to devise innovative solutions that can overcome these challenges.

The competition opens on November 25, 2025, and runs until January 19, 2026, providing ample time for participants to develop their methods and contribute to the advancement of space exploration technology. By engaging the public and leveraging collective ingenuity, NASA hopes to enhance its capabilities in lunar exploration, ultimately paving the way for more ambitious missions to the Moon and beyond.
